Cardboard Bicycle Could Change the World

First cardboard restaurants, now cardboard bicycles—Israeli inventor Izhar Gafni spent years developing a bicycle that is made almost completely of cardboard and sells for a mere $20.

No metal parts will be used on the final product, which will go into production in the next few months. The bicycle is composed of an entirely organic “secret concoction” that makes it durable, waterproof, fireproof and recyclable.
